The proper firmware for wl12xx support is available from: git://git.kernel.org/pub/scm/linux/kernel/git/romieu/linux-firmware.git, just clone that repository and copy the ti-connectivity directory to /lib/firmare/.

Building 2.6.39-rc1 is basically the same as [[Panda_How_to_kernel_2_6_38|How to build 2.6.38 kernel]], but of course you need the rc1 sources. The omap4430panda_config works, but does not enable anything interesting. [[Media:config.2.6.39-rc1|config.2.6.39-rc1]] enables USB, its' ethernet adapter, and wl12xx support.

* Update 5/9/2011 A newer version is available from: git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git which includes a Bluetooth init script, which contains binary patches to the firmware that resides in ROM.

* This OMAP35xx App note also is interesting: http://processors.wiki.ti.com/index.php/OMAP35x_Wireless_Connectivity_WLAN_Bluetooth_Coexistence_Application_Note

+

* The firmware and wl1271 hardware is the same as on the PandaBoard, but there is no support in /arch/arm/mach-omap2/board-omap4panda.c for the gpio's that control BT_EN (GPIO46) or BT_WAKEUP (GPIO49), as well as the bt audio interface to MCBSP1. In addition, the latest Bluez (4.93) source for hidattach_ti.c still assumes that the firmware (and bt init script) are in /lib/firmware/ rather than in /lib/firmware/ti-connectivity/. The new firmware does work for wlan.

== Building ==

Building 2.6.39-rc1, -rc3, -rc5, or -rc6 is basically the same as [[Panda_How_to_kernel_2_6_38|How to build 2.6.38 kernel]], but of course you need the rc1/3/5/6 sources. The omap2plus_defconfig works, but does not enable anything interesting. [[Media:config.2.6.39-rc1|config.2.6.39-rc1]] enables USB, its' ethernet adapter, and wl12xx support. Or [[Media:config.2.6.39-rc3.1|config.2.6.39-rc3.1]] for -rc3. [[Media:config.2.6.39-rc1.2|config.2.6.39-rc1.2]] enables USB, it's ethernet adapter, wl12xx support, and dvi support, for -rc3 use [[Media:config.2.6.39-rc3.3|config.2.6.39-rc3.3]], [[Media:config.2.6.39-rc5.1|config.2.6.39-rc5.1]] for -rc5 and [[Media:config.2.6.39-rc6.1|config.2.6.39-rc6.1]] for -rc6. However using either of those configs requires that the kernel sources be patched with [[Media:0001-omap4-pandaboard-fix-dvi-support.patch|0001-omap4-pandaboard-fix-dvi-support.patch]] The patch also provices panda_dvi_defconfig which just enables dvi. This patch applies to both -rc1, -rc3, -rc5 and -rc6.

Introduction

The merge window has closed and 2.6.39-rc1 has been released, There are many Pandaboard related changes, including HDMI, DVI and wl21xx support.

-rc1

* hdmi & dvi are broken due to some dss clocking issues, see: https://patchwork.kernel.org/patch/674062/ for details, a fix for dvi is available, see below.
* abe sound is not supported.
* Dave Anders patch to not configure the unused power regulators of VUSIM and VAUX1 is included.
* wl12xx support is working to the extent that one can associate with an access point, get an IP address and ping out to the internet.

-rc2

* Neither OMAP nor PandaBoaqrd changes, no other changes to wlan, dvi or hdmi code, so stay tuned for rc-3 in about a week or so.
** looks like lots of interesting changes queued up for the next -rc so stay tuned..

-rc3

* Rebooting is broken (there was a post suggesting that it was broken in -rc2 as well) follow
this thread for more info: http://www.spinics.net/lists/linux-omap/msg49746.html.
** a simple fix is to turn off OMAP2 support, which is done in the .config below for -rc3.
* What at first looked like interesting changes to /arch/arm/mach-omap2/ /drivers/net/wireless/wl12xx/ /drivers/video/omap2/dss/
seemed to really be typo fixes in comments, Hopefully, some real fixes will be in -rc3.
* New in -rc3 is that the usb ethernet adapter appears as eth0 rather than usb0.

-rc4

* Neither OMAP nor PandaBoaqrd changes, no other changes to wlan, dvi or hdmi code, so stay tuned for rc-5 in about a week or so.

-rc5

* Neither OMAP nor PandaBoaqrd changes, no other changes to wlan, dvi or hdmi code,
* There have been lots of changes in other parts of the kernel, so it's time to see if anything in -rc5 breaks pandaboard.
* Rebooting is still broken, so beware of using omap2plus_defconfig without changes. (see -rc3 above)
* patching is still neccessary to get dvi working
* wlan and ethernet both seem to work as in -rc3
** There are several omap44xx changes queued up for -rc6

-rc6

* lots of (real) changes for omap, see http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.39-rc6 for details.
* Rebooting is still broken, so beware of using omap2plus_defconfig without changes. (see -rc3 above)
* patching is still neccessary to get dvi working
* wlan and ethernet both seem to work as in -rc3, -rc4 and -rc5
* i2c chararacter device driver is still broken, the patch below still applies cleanly and resolves the issue.

-rc7

* No specific PandaBoard changes, but there was work done on /drivers/usb/host/ehci-omap.c
* A new version of wlan firmware (see below) is available which might have working bluetooth.
unfortunately, there is no BT support in the board file /arch/arm/mach-omap2/board-omap4panda.c
* looks like some PandaBoard & OMAP4 specific changes queued up for the next .39-rcx (or maybe .40-rc1)

The firmware and wl1271 hardware is the same as on the PandaBoard, but there is no support in /arch/arm/mach-omap2/board-omap4panda.c for the gpio's that control BT_EN (GPIO46) or BT_WAKEUP (GPIO49), as well as the bt audio interface to MCBSP1. In addition, the latest Bluez (4.93) source for hidattach_ti.c still assumes that the firmware (and bt init script) are in /lib/firmware/ rather than in /lib/firmware/ti-connectivity/. The new firmware does work for wlan.
